ICMP messages <- what are they doing?

ICMP messages <- what are they doing?

Post by Albert E. Wha » Wed, 14 Feb 1996 04:00:00

I've had a few problems lately with some hardware.  Last night I lost
the functionality of our Network Systems Router.  Today I lost the
functionality of the Annex Terminal Server (I REALLY Hate when this
happens!  ;-<).  In any event, I have seen many, many, many ,many
.... (you get the idea) messages regarding ICMP.  Like the following:

Oct 24 13:17:28 annex1.hky.com root[0]: icmp: received REDIRECT to from for while running routed

Oct 24 13:17:29 annex1.hky.com last message repeated 107 times

Is this someone trying to ping me, enough to*up the router
requiring a cold reset!

It's my understanding that these are PING messages.  Is that true?
Should I shield the network from them?  Any ideas are greatly


1. calcru: negative time <<< Why am I getting this message?

I've just upgraded to 2.2.6, and I am getting messages like
this from the kernel:

calcru: negative time: -xxx usec

where xxx is some 3 or 4 digit number.

What can I do to fix this?

Thanks in advance.
